    Sesame is a key oilseed crop predominantly cultivated in Northern and Eastern regions of Uganda. Despite efforts to promote sesame production, adoption of improved agronomic practices remains low. This study assesses adoption intensity, determinants of improved agronomic practices, and opportunities for enhancing sesame production in Northern Uganda. The study employed multi-stage and purposive sampling to survey 123 sesame farmers in Lira and Kole districts. Results indicate a 50% adoption intensity for ten critical agronomic practices. Highly adopted practices included early planting (91.9%), weeding (88.6%), crop rotation (72.4%), timely harvesting (90.2%), and proper post-harvest handling (96.7%). Conversely, the least adopted practices were use of improved sesame varieties, recommended spacing, pesticides, fungicides, and fertilizers. A Tobit regression model revealed that young, unmarried farmers with lower education levels, but farming as their primary occupation and having 4-6 years of production experience, exhibited higher acceptance and adoption rates of improved agronomic practices. Overall, addressing challenges such as drought, declining soil fertility, pests and diseases, limited market access, and constraints in inputs and credit is crucial for increasing adoption of improved agronomic practices in sesame production.

    Evaluation of Improved Cowpea Genotypes for Yield and Resistance to Scab Disease in Uganda
    (Medwin Publishers, 2023-11-10) Alipa, Jorem; A, Charles; A, Robert; L, Geofrey; M, Emmanuel; wacal, Cosmas
    Cowpea is one of the most important legume food crops in Uganda. However, grain yields as low as 400 kg ha−1 have been recorded in farmers’ fields despite a grain yield potential of 3,000 kg ha−1. Cowpea scab is a major production constraint, causing yield losses of up to 100%. Three hundred ninety (390) improved cowpea genotypes were evaluated for yield and scab resistance for one (1) year at NaSARRI, Serere, Uganda using an alpha lattice design with two replications. The analysis of variance showed significant differences (p < 0.05) for grain yield, scab severity, incidence, and area under disease progress curve (AUDPC) among genotypes, seasons, and for genotypes by seasons interactions. The mean grain yield of 981.6 kg ha−1 was recorded across the cowpea genotypes with genotype, TVU-1280 having the highest grain yield of 1790.8 Kg ha−1. The cowpea genotypes; 1195K-1093-5-A, TVU-2968, SanZi, Taef-14-inhaca.E, TVU-205-8 and TVU-13485 had low scab severity(range:8.0 - 9.0).Cowpea genotypes; Taef-14-inhaca.E(33.7%), TVU-14633(26.7%), TVU-151144(30.6%), and Cosiriele (31.4%), had low scab incidence. Low AUDPC (range: 788.8-883.5) was observed in cowpea genotypes; 1195K-1093-5-A (775.0), TVU2968(788.8), TVU-14633-A (883.8), and TVU-13388 (857.5). Grain yield had a significant negative correlation with AUDPC (r = −0.2279, p < 0.001) and scab severity (−0.600, p < 0.001). Scab severity showed a strong significant and positive correlation with AUDPC (r = 0.6873, p < 0.001). The cowpea genotypes; 1195K−1093−5−A, TVU−2968, TVU−15114, SanZi, and Taef−14− inhaca.E could be used as breeding lines for introgressing scab resistance into cultivars with farmer preferred traits.

    Unravelling the potential benefits of sesame (Sesamum indicum L.) incropping systems, nutritional, health, and industrial uses of its seeds –a review
    (Taylor & Francis, 2024-05-23) Wacala, Cosmas; Musinguzi, Simon Peter; Ewaju, Emmanuel; Atibo, Christopher; Alowo, Docus; Alipa, Jorem; Basalirwa, Daniel
    Sesame (Sesamum indicum l.) is considered as one of the important oilseed crops produced throughout the world especially in the tropical and sub-tropical regions. Sesame crop is grown mainly for its highly nutritious seeds that also offer medicinal value. Sesame seed is rich in edible oil, fatty acids mainly linoleic acid and oleic acid, lignans, tocopherols, phytosterols, phenolic acids, and minerals. Due to these essential contents, the consumption of sesame seeds promotes good health not only in humans but also in livestock. Hence, sesame crop has gained significant attention throughout the world due to its several benefits. Although the global production of sesame is increasing, there is need to understand its various uses right from benefits in cropping systems to nutritional, health and industrial level. Several reviews have been conducted with the central focus on sesame nutritional and health promoting benefits but none has provided a holistic review of its benefits in cropping systems such as intercropping sesame with other crops, inclusion in crop rotation, utilization of its crop residues as nutrient recycling, and nutritional, health and industrial uses of sesame seeds, which this study sought to address.
